Description

Technical Field

[0001] The present invention relates to the technical field of high-pressure homogenization equipment, and particularly relates to an adjustable-gap high-pressure micro-jet impinging homogenization valve structure and a homogenization method. Background Art

[0002] Currently, the commonly used homogenizers include micro-jet homogenizers and valve-type high-pressure homogenizers. The cavity of the opposed-jet Y-type micro-jet homogenizer has a fixed gap and a fixed flow channel. However, during the homogenization process, the viscosity of the material often changes greatly, resulting in different flow resistances in the fixed gap or fixed flow channel. Traditional micro-jet equipment can only adjust and adapt to the homogenization pressure by controlling the pressure of the hydraulic pump station and the thrust of the oil cylinder, or replacing the cavity with different gap values or different fixed flow channel aperture sizes, which affects the homogenization efficiency. The homogenization valve structure of the valve-type high-pressure homogenizer usually adopts a wall-impinging valve structure that diffuses from the inner circle to the outer circle. The material generates an impact force to break the material by hitting the valve wall. However, this diffusion impact method has a single speed. When dealing with some materials that are difficult to break and disperse, such as cerium oxide, alumina, graphene, carbon nanotubes with a Mohs hardness greater than a certain value, and fibrous materials with a relatively large aspect ratio, etc., there are problems of insufficient impact force. It often requires homogenization many times in a cycle, with low production efficiency, extremely high investment and production energy consumption costs, and the wall impact will also cause cutting grooves in the inner ring of the impact ring, thereby generating impurities and affecting the purity of the material.

[0049] Referring to Figures 1 to 6 , the adjustable-gap high-pressure micro-jet impinging homogenization valve structure according to the first aspect embodiment of the present invention includes a valve body 100, a homogenization valve seat 200, a homogenization valve core 300, and an adjustment device 400. The valve body 100 is provided with a homogenization channel 110. The homogenization valve seat 200 is fixedly installed in the homogenization channel 110. The homogenization valve core 300 is slidably installed in the homogenization channel 110. The adjustment device 400 is used to drive the homogenization valve core 300 to slide so as to adjust the distance between the homogenization valve core 300 and the homogenization valve seat 200. Referring to Figure 3 , Figure 4 As shown in Figure 1 , Figure 2 , the homogenization valve seat 200 is provided with a plurality of diversion channels 210 penetrating through the homogenization valve seat 200, and the plurality of diversion channels 210 are arranged at intervals around the circumference; as shown in Figure 1 , Figure 2 , the homogenization valve core 300 is slidably installed in the homogenization channel 110; a jet cavity is formed between the homogenization valve core 300 and the homogenization valve seat 200; a discharge hole 310 is provided at the center of the homogenization valve core 300, and an impact cavity 301 is formed between the end of the discharge hole 310 and the homogenization valve seat 200. The impact cavity 301 is located at the center of the jet cavity; the discharge hole 310 is aligned with the center of the homogenization valve seat 200. The material enters the jet cavity through the diversion channels 210, and then collides in the impact cavity 301 and enters the discharge hole 310. In the adjustable-gap high-pressure micro-jet impinging homogenization valve structure of this embodiment, by guiding the material into the impact cavity 301 for collision, compared with the method of crushing the material by impacting the valve wall, the speed and impact force of the aggregated impact of the material in this embodiment are approximately twice that of the wall-impacting type, and it can also avoid generating foreign objects by cutting the valve wall, thereby improving the purity of the material; by adjusting the distance between the homogenization valve seat 200 and the homogenization valve core 300 through the adjustment device 400, the homogenization pressure can be adjusted in real time according to the running state of the material, ensuring the constant-pressure homogenization of the material, improving the homogenization quality and production efficiency, and enhancing the safety of the equipment.

[0050] In order to further improve the collision effect of the material, the homogenizing valve seat 200 and the homogenizing valve core 300 of this embodiment are preferably coaxially arranged, and the central axis of the discharge hole 310 coincides with the axis of the homogenizing valve core 300; and a first matching structure 220 is provided on the end face of the homogenizing valve seat 200 facing the homogenizing valve core 300; and / or, a second matching structure 320 is provided on the surface of the homogenizing valve core 300, and the first matching structure 220 and the second matching structure 320 are arranged to fit at a set impact angle and coaxially. Specifically, in this embodiment, it may be that the end face of the homogenizing valve seat 200 facing the homogenizing valve core 300 does not have a first matching structure 220 protruding from its surface, and the outer periphery of the discharge hole 310 also does not have a second matching structure 320 protruding from the surface of the homogenizing valve core 300; or, it may also be that the end face of the homogenizing valve seat 200 facing the homogenizing valve core 300 has a first matching structure 220 protruding from its surface, and the outer periphery of the discharge hole 310 does not have a second matching structure 320 protruding from the surface of the homogenizing valve core 300; or, it may also be that the end face of the homogenizing valve seat 200 facing the homogenizing valve core 300 does not have a first matching structure 220 protruding from its surface, and the outer periphery of the discharge hole 310 has a second matching structure 320 protruding from the surface of the homogenizing valve core 300; or, it may also be that the end face of the homogenizing valve seat 200 facing the homogenizing valve core 300 has a first matching structure 220 protruding from its surface, and the outer periphery of the discharge hole 310 has a second matching structure 320 protruding from the surface of the homogenizing valve core 300. If both the first matching structure 220 and the second matching structure 320 are provided, it is preferred that the shapes and sizes of the first matching structure 220 and the second matching structure 320 are the same; the first matching structure 220 and the second matching structure 320 can adopt Figure 3 the circular shape shown or Figure 4 the rectangular shape shown, or can also adopt one or more of an oval shape, a polygon shape, etc., which are not limited in this embodiment and can be specifically set according to actual requirements.

[0051] It should be understood that by setting the first mating structure 220 and / or the second mating structure 320, the pressure of the material can change when it enters the impact chamber 301 from the jet chamber. For example, it can instantaneously change from a high pressure state to a low pressure state, generating a powerful cavitation effect and shear effect, thereby improving the crushing effect of the material. By changing the distance between the valve core and the valve seat, parameters such as pressure, impact force, shear force, and impact speed can be changed. In this embodiment, the high-pressure material enters from the feed end of the homogenization channel 110, then impacts the center of the homogenization valve seat 200 and diffuses outward to the outer circle, flows through the diversion channel 210, and then flows to the outer ring position of the homogenization valve core 300 and enters the jet chamber. The high-pressure material in the jet chamber enters the impact chamber 301 from the 360-degree outer ring direction and collides with each other at high speed at the center point of the impact chamber 301, forming an opposite thin-sheet type collision flow or mutual collision flow. The closer to the center point of the impact chamber 301, the greater the impact force between the materials. When the high-pressure material passes through the gap between the first mating structure 220 and the second mating structure 320, a powerful shear force is generated. Combining with the powerful mutual impact force, high-efficiency homogenization effects such as particle size refinement, remixing, and coating of the material are obtained. The first mating structure 220 and the second mating structure 320 are set to fit at a set impact angle. The set impact angle can be 180 degrees to enable the materials to collide horizontally; the set impact angle is less than 180 degrees to enable the materials to collide at an angle.

[0052] Referring to Figure 3 、 Figure 4 As shown, in the embodiment of the present invention, a groove 221 is provided at the center of the first mating structure 220. The groove 221 is aligned with the discharge hole 310, that is, the center position of the first mating structure 220 is hollow. After the material enters the impact chamber 301 through the gap between the first mating structure 220 and the second mating structure 320, the pressure will instantaneously change from a high pressure state to a low pressure state, thereby generating a powerful cavitation effect and shear effect, improving the crushing effect of the material.

[0053] Furthermore, in the embodiment of the present invention, a chamfer is provided at the end of the discharge hole 310 facing the homogenization valve seat 200. The setting of the chamfer can increase the volume of the impact chamber 301, thereby enabling the high-pressure material to pass through the gap between the first mating structure 220 and the second mating structure 320 and enter the impact chamber 301 to generate a huge pressure drop, thereby enhancing the cavitation effect and crushing effect on the material. In addition, providing a chamfer at the end of the discharge hole 310 facing the homogenization valve seat 200 can also facilitate the material to quickly enter the discharge hole 310 and be discharged.

[0054] Referring to Figure 2 As shown, by changing the outer diameter D1 and the inner diameter D2 of the second mating structure 320, the regulation of the material pressure, impact speed, and impact force can be achieved. When homogenizing different materials, the sizes of D1 and D2 can be modified as appropriate.

[0055] In the above embodiments, when the material enters the impact chamber 301 from the gap between the first mating structure 220 and the second mating structure 320, due to the flatness errors of the surfaces of the first mating structure 220 and the second mating structure 320, the unit flow rate passing through each gap may be different, which affects the collision effect. Therefore, another technical solution is proposed in this scheme. The end face of the homogenizing valve seat 200 facing the homogenizing valve core 300 is still provided as Figure 3 , Figure 4 shown, the first mating structure 220 protruding from the surface of the homogenizing valve seat 200, but as Figure 5 shown, at least two symmetrically arranged flow channels are provided on the end face of the first mating structure 220. When the first mating structure 220 is in contact with the homogenizing valve core 300 or the second mating structure 320, the symmetric flow channels form a collision channel 230. In this way, the material can collide in a clustered manner in a thin-sheet or wire-bundle form to suit different types of materials.

[0056] It can be imagined that the collision channel 230 can be provided on the first mating structure 220, or on the second mating structure 320, or collision channels 230 can be provided on both the first mating structure 220 and the second mating structure 320. Specifically, a suitable technical solution can be adopted according to the actual situation.

[0057] Furthermore, as can be seen from the above, the first mating structure 220 may not be provided on the homogenizing valve seat 200 in this embodiment. In this case, the collision channel 230 can also be provided on the end face of the homogenizing valve seat 200 facing the homogenizing valve core 300, for example Figure 6 shown; at the same time, multiple collision channels 230 can intersect at the center position of the impact chamber 301, or there can be multiple parallel collision channels 230, or there can be both parallel and intersecting collision channels 230 at the same time, which can be specifically set according to the actual situation.

[0058] It should be noted that the cross-sectional shape of the collision channel 230 can refer to the Figure 5 shown rectangle, or the Figure 6 shown semi-circle. The cross-sectional shape of the collision channel 230 can also be in the form of special shapes, polygons, ellipses, etc., which are not limited in this embodiment and can be specifically set according to the actual situation.

[0059] The properties of different materials vary, so the homogenization pressure, etc. will also change accordingly. To adapt to different materials, different pore diameters or shapes of the diversion channels 210 and / or different pore diameters or shapes of the discharge holes 310 can be adopted. Specifically, the cross-sectional shape of the diversion channel 210 can be one or more of circular, elliptical, polygonal, and irregular shapes, and the cross-sectional shape of the discharge hole 310 can also be one or more of circular, elliptical, polygonal, and irregular shapes, which are not limited in this embodiment. Further, for different materials, in order to generate greater physical forces such as turbulence, laminar flow, impact, and shear, the Figure 2 inner diameters D3 and / or D4 of the discharge hole 310 shown in

[0060] The homogenization method according to the second aspect embodiment of the present invention is applicable to the above adjustable-gap high-pressure micro-jet impinging homogenization valve structure; the homogenization method includes the following steps:

[0061] S1. Detect the first set parameter of the material;

[0062] S2. Set the distance between the homogenization valve core 300 and the homogenization valve seat 200 to the first set distance corresponding to the first set parameter;

[0063] S3. Perform homogenization operation and run for the first set number of times;

[0064] S4. Detect the first set parameter and the second set parameter of the material;

[0065] S5. If the first set parameter is greater than the first preset value, execute the control strategy; if the first set parameter is less than or equal to the first preset value, output the material;

[0066] The control strategy is: compare the second set parameter with the second preset value. If the second set parameter is greater than the second preset value, increase the first set distance; if the second set parameter is less than the second preset value, decrease the first set distance;

[0067] S6. Repeat steps S3 to S5.

[0068] In the embodiment of the present invention, the first set parameter is the particle size distribution range value. The particle size distribution range values of different materials are different, and at the same time, the particle size distribution range values of the material before and after homogenization are also different. Usually, before the material is subjected to the homogenization operation, the particle size distribution range value of the material is greater than the particle size distribution range value after homogenization; when the particle size distribution range value after homogenization is less than the first set value, it usually means that the material meets the requirements for homogenization.

[0069] It can be imagined that the first set parameter can also be other parameters according to the actual situation.

[0070] Furthermore, the second set parameter in this embodiment is the viscosity or pressure value of the material. During the homogenization cycle of most micro-nano materials, after their particle sizes become smaller, their specific surface areas become very large, and the viscosity of the material will increase exponentially, resulting in an increase in flow resistance. At this time, when the flow rate or flow volume remains unchanged, the homogenization pressure will increase significantly due to the increase in viscosity and may even exceed the safety pressure and trigger an alarm. Currently, the common solutions are, one is to reduce the flow rate, and the other is to replace the microchannel cavity or homogenization valve assembly with a larger flow capacity to adapt to the changes in different viscosities during the homogenization process. Reducing the flow rate will lead to a decrease in equipment efficiency, and replacing the microchannel cavity or homogenization valve assembly with a larger flow capacity is troublesome to operate. The adjustable-gap high-pressure microjet impinging homogenization valve structure of the present application can, when the viscosity changes during the cycle, avoid changing the equipment operating speed or frequently replacing the cavity of the fixed microchannel and the homogenization valve assembly. When the equipment monitors changes in the material viscosity or pressure, it can automatically adjust the gap between the homogenization valve seat 200 and the homogenization valve core 300 to achieve continuous constant-pressure homogenization, maximizing the production efficiency and homogenization quality of the equipment.

[0071] In the embodiment of the present invention, the first preset value and the second preset value are pre-stored in the control system for controlling the adjustable-gap high-pressure microjet impinging homogenization valve structure and can be manually stored or modified. A set spacing is also preset in the control system. If the second set parameter is greater than the second preset value, the first set spacing is increased by the set spacing; if the second set parameter is less than the second preset value, the first set spacing is reduced by the set spacing. The first preset value and the second preset value may vary according to different materials. At the same time, the second preset value is preferably a range value. The set spacing can be changed by the operation of the adjusting device 400 to suit the actual production situation.

[0072] The adjustable-gap high-pressure microjet impinging homogenization valve structure of the embodiment of the present invention usually further includes a pressure detection device for detecting the pressure in the impact chamber 301 or the jet chamber. When the detected actual pressure value of the material exceeds the set pressure value, the adjusting device 400 is required to drive the homogenization valve core 300 to move away from the homogenization valve seat 200 to reduce the homogenization pressure, so as to achieve constant-pressure homogenization to the greatest extent and improve the safety of the equipment at the same time.

[0073] The adjustable-gap high-pressure microjet impinging homogenization valve structure of the embodiment of the present invention can read data such as flow rate, pressure, temperature, and viscosity in the production process in real time. By embedding an AI model optimization design program in a computer or PLC, it can identify the homogenization characteristics of the material under different gaps, different pressures, different particle sizes, different solid contents, different flow rates, different temperatures, etc., and automatically adjust the gap between the homogenization valve core 300 and the homogenization valve seat 200 in real time, accurately control the homogenization pressure, and achieve the homogenization goal of the material in the most efficient and energy-saving production method.
